PHOSPHOR CONVERTED OLED ILLUMINATION DEVICE

摘要

The invention relates to an illumination device (40) comprising a blue and/or a green emitting OLED (Ob, Og) and a converter layer (C_yr). The converter layer (C_yr) comprises at least one luminescent material selected from the group consisting of a) (Zn1-xCdx)(S1-ySey) and (In1-xGax)(P1-yAsy) with x, y ? [0, 1]; b) uranine, rhodamine 6G, and rhodamine B; c) complexes of Ir3+; d) complexes of Tb3+; e) the complexes [Eu(acac)3(X)], [Eu(ttfa)3(X)], [Eu(thd)3(X)], and [Eu(dibenzoylmethane)3(X)] with X = bipyridine, phenanthroline, diphenylphenathroline and further derivatives; and f) SrLi2SiO4:Eu, (Ba,Sr)2SiO4:Eu, and (Ca,Sr)2SiO4 :Eu.
